                     score="0.014"
                     href="http://www.medpagetoday.com/Rheumatology/Arthritis/tb/18379?impressionId=1265819395716"
                     
      &lt;p&gt;Elderly men with low serum levels of vitamin D are at increased risk for developing hip osteoarthritis, a prospective cohort study found.&lt;/p&gt;
&lt;p&gt;Men whose levels of 25-hydroxyvitamin (OH)D were between 15.1 to 30 ng/mL had twice the likelihood of prevalent radiographic hip osteoarthritis than those whose levels were normal (OR 2.19, 95% CI 1.21 to 3.97), according to R. Krishna Chaganti, MD, of the University of California at San Francisco, and colleagues.&lt;/p&gt;
&lt;p&gt;Conversely, after adjusting for age, season at blood draw, and clinic site, higher vitamin D levels were associated with a lower prevalence of hip osteoarthritis (OR 1.39 per 1 SD decrease in 25(OH)D level, 95% CI 1.11 to 1.74), the researchers reported in the February issue of &lt;em&gt;Arthritis &amp;amp; Rheumatism&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;Because the role vitamin D may play in the pathogenesis and progression of osteoarthritis is unclear, Chaganti and colleagues analyzed data from the Osteoporotic Fractures in Men Study, which enrolled a large cohort of elderly men between 2000 and 2002 from six centers across the U.S.&lt;/p&gt;
&lt;p&gt;A total of 1,104 men whose mean age was 77.2 years had baseline measurements of serum vitamin D, and about 4.5 years later pelvic radiographs were obtained.&lt;/p&gt;
&lt;p&gt;Radiographs were scored to reflect joint space narrowing, osteophyte formation, cysts, subchondral sclerosis, and femoral head deformity.&lt;/p&gt;
&lt;p&gt;Vitamin D levels were categorized as deficiency (&amp;#8804;15 ng/mL), insufficiency (15.1 to 30 ng/mL), and sufficiency (&amp;gt;30 ng/mL).&lt;/p&gt;
&lt;p&gt;Mean vitamin D level was 23.38 ng/mL in men who had radiographic hip osteoarthritis, compared with 26.04 ng/mL in men without radiographic abnormalities (&lt;em&gt;P&lt;/em&gt;=0.0002).&lt;/p&gt;
&lt;p&gt;Men with hip osteoarthritis had a higher prevalence of both vitamin D insufficiency (77% versus 65%, &lt;em&gt;P&lt;/em&gt;=0.002) and deficiency (10.2% versus 7.5%, &lt;em&gt;P&lt;/em&gt;=0.012).&lt;/p&gt;
&lt;p&gt;Moreover, they had slower six-meter walking speed (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.0001) and reported more hip pain (&lt;em&gt;P&lt;/em&gt;=0.0001).&lt;/p&gt;
&lt;p&gt;Men who were vitamin D deficient also tended to have an increased likelihood of hip osteoarthritis (OR 1.99, 95% CI 0.83 to 4.74), but after adjustment in multivariate models, statistical significance was lost with this level of the vitamin.&lt;/p&gt;
&lt;p&gt;&quot;The association of low 25(OH)D levels with prevalent radiographic hip [osteoarthritis] underscores the potentially important role of vitamin D in the pathogenesis of [osteoarthritis]. Vitamin D metabolites have been found to be associated with the regulation of the Wnt pathway, products of which play important roles in the development and maintenance of bone and cartilage,&quot; the investigators explained.&lt;/p&gt;
&lt;p&gt;Furthermore, in vitro studies have suggested that serum levels of 25-hydroxyvitamin D&lt;sub&gt;3&lt;/sub&gt; can affect the ratio of RANKL to osteoprotegerin and thereby influence bone deterioration and repair.&lt;/p&gt;
&lt;p&gt;Previous investigations have yielded conflicting results. One study found that low levels of vitamin D were not associated with worsening of knee osteoarthritis, as reflected in loss of articular cartilage on MRI.&lt;/p&gt;
&lt;p&gt;Another study, however, linked knee osteoarthritis with low vitamin D levels, particularly in patients who also had decreased bone mineral density in the lumbar spine.&lt;/p&gt;
&lt;p&gt;&quot;Vitamin D influences the mineralization of bone matrix, and low serum levels of vitamin D may result in poorly mineralized bone that might alter forces across the joint and reduce joint deterioration,&quot; the authors suggested.&lt;/p&gt;
&lt;p&gt;On the other hand, low levels may interfere with chondrocyte metabolism and thereby increase degeneration.&lt;/p&gt;
&lt;p&gt;Further studies will be needed to more fully clarify the effects of the vitamin on the development and progression of osteoarthritis, the investigators cautioned.&lt;/p&gt;
&lt;p&gt;Strengths of the study include the large cohort of participants, careful classification of radiographic osteoarthritis, and reliance on the gold standard of vitamin D measurement, the 25(OH)D level.&lt;/p&gt;
&lt;p&gt;Limitations include the cross-sectional design, precluding the inference of causality, and the gap in time between measurement of serum vitamin D and radiography.&lt;/p&gt;
&lt;p&gt;The authors concluded that therapeutic interventions to increase vitamin D serum levels in the elderly &quot;are warranted,&quot; with the goal of improving skeletal health in this vulnerable age group.&lt;/p&gt;

                     score="0.005"
                     href="http://www.medpagetoday.com/Geriatrics/GeneralGeriatrics/tb/18173?impressionId=1265819395716"
                     
      &lt;p&gt;Raising seniors&apos; copayments for ambulatory care to offset increasing healthcare costs may backfire on insurers, researchers asserted.&lt;/p&gt;
&lt;p&gt;Seniors enrolled in Medicare plans that increased copayments had significantly fewer outpatient visits but spent more time in the hospital than patients in plans that left copayments untouched, according to Amal Trivedi, MD, MPH, of Brown University in Providence, R.I., and colleagues.&lt;/p&gt;
&lt;p&gt;Assuming an average reimbursement of $60 for an outpatient visit, seven annual visits per enrollee, and an average copay increase of $8.50 per visit, a plan should save $7,150 for every 100 enrollees, they noted in the Jan. 28 &lt;em&gt;New England Journal of Medicine&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;But, assuming an average cost of $11,065 per hospitalization of a person 65 to 84, the researchers estimated that the costs for inpatient care would actually increase by $24,000 for every 100 enrollees in the year after copays are increased.&lt;/p&gt;
&lt;p&gt;Even using more conservative criteria, the increased costs for inpatient care would nearly double any savings from increasing copays, they argued.&lt;/p&gt;
&lt;p&gt;&quot;Cost-sharing has generally been thought to reduce total healthcare spending without harming health for the average person,&quot; the researchers wrote, but these results suggest increasing copays in Medicare beneficiaries &quot;may be a particularly ill-advised cost-containment strategy.&quot;&lt;/p&gt;
&lt;p&gt;Increasing copayments may be particularly harmful to older patients, they said, because they have lower incomes and are more likely to have poor health and greater out-of-pocket healthcare expenses than younger patients.&lt;/p&gt;
&lt;p&gt;To explore the issue in a Medicare population, Trivedi and colleagues compared the use of outpatient and inpatient care between enrollees in 18 plans that increased copays for ambulatory care and 18 that did not. The study included 899,060 patients.&lt;/p&gt;
&lt;p&gt;According to data from the Medicare Healthcare Effectiveness Data and Information Set from the Centers for Medicare and Medicaid Services, mean copays increased during the study period for both primary care ($7.38 to $14.38) and specialty care ($12.66 to $22.05) in the case plans.&lt;/p&gt;
&lt;p&gt;Mean copays remained stable at $8.33 and $11.38 for primary and specialty care, respectively, in the control plans.&lt;/p&gt;
&lt;p&gt;In both groups, there were increases in the number of ambulatory visits over time, but the increase was smaller in the plans that raised copays.&lt;/p&gt;
&lt;p&gt;There was also a rise in the number of hospitalizations, the proportion of patients who were hospitalized, and the length of time spent in the hospital in both groups, but there were larger increases in the plans that increased copays.&lt;/p&gt;
&lt;p&gt;Compared with the control plans, in the year after the increase in copays, case plans had: &lt;ul&gt; &lt;li&gt;19.8 fewer annual outpatient visits per 100 enrollees (95% CI 16.6 to 23.1)&lt;/li&gt; &lt;li&gt;2.2 additional annual hospital admissions per 100 enrollees (95% CI 1.8 to 2.6)&lt;/li&gt; &lt;li&gt;13.4 more annual inpatient days per 100 enrollees (95% CI 10.2 to 16.6)&lt;/li&gt; &lt;li&gt;A 0.7% increase in the proportion of enrollees who were hospitalized (95% CI 0.51% to 0.95%)&lt;/li&gt; &lt;/ul&gt;&lt;/p&gt;
&lt;p&gt;The findings were amplified among enrollees living in areas of lower income and education, black patients, and those who had hypertension, diabetes, or a history of myocardial infarction.&lt;/p&gt;
&lt;p&gt;Trivedi and colleagues noted some limitations of the analysis: it was not randomized, and unmeasured differences could have influenced the results.&lt;/p&gt;
&lt;p&gt;Also, the case and control plans could not be matched in a geographic area smaller than census region because of the small number of Medicare plans, and data were lacking on diagnoses, procedures, and costs associated with hospital admissions and outpatient visits.&lt;/p&gt;

                     score="0.005"
                     href="http://www.medpagetoday.com/HematologyOncology/ColonCancer/tb/18164?impressionId=1265819395716"
                     
      Patients 65 and older are as suitable as younger individuals for CT colonography, said researchers conducting a large retrospective study.&lt;br&gt;
&lt;br&gt;Advanced neoplasias were detected with CT colonography  --  often called &quot;virtual colonoscopy&quot;  --  in older patients at more than double the rate in the general screening population, reported David H. Kim, MD, of the University of Wisconsin in Madison, Wis., and colleagues in the February issue of &lt;em&gt;Radiology&lt;/em&gt;.&lt;br&gt;
&lt;br&gt;They found that 7.6% of older patients had advanced neoplasias, compared with 3.2% of all patients screened in the university&apos;s clinic (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.001).&lt;/p&gt;
&lt;p&gt;On the basis of this and other findings in 577 individuals 65 and older versus the entire group of 3,120 patients undergoing the procedure, Kim and colleagues concluded that &quot;CT colonography performance is maintained in an older cohort.&quot;&lt;/p&gt;
&lt;p&gt;&quot;Overall, the observations from this clinical experience confirm that CT colonography may be a valuable screening modality in the older population,&quot; they wrote.&lt;/p&gt;
&lt;p&gt;On the other hand, the study did not address several objections raised by the Centers for Medicare and Medicaid Services (CMS) in its decision last year to deny Medicare coverage for the procedure. (See &lt;a href=&quot;http://www.medpagetoday.com/PublicHealthPolicy/Medicare/14186&quot; mce_href=&quot;http://www.medpagetoday.com/PublicHealthPolicy/Medicare/14186&quot; target=&quot;_blank&quot;&gt;Medicare Finalizes Denial of Virtual Colonoscopy Coverage&lt;/a&gt;)&lt;/p&gt;
&lt;p&gt;CMS had pointed to relatively low sensitivity of CT colonography compared with optical colonoscopy in prospective trials, especially for small lesions.&lt;/p&gt;
&lt;p&gt;The agency also determined that CT colonography increased the costs of positive findings, since abnormalities in the CT scans must be confirmed with optical colonoscopy. In addition, CMS said there was no evidence to support claims that the less invasive imaging procedure would be more acceptable to patients and therefore would raise screening rates.&lt;/p&gt;
&lt;p&gt;The data analyzed by Kim and colleagues did not allow for calculations of false-negative rates or predictive values of positive or negative findings. Nor did the researchers report cost information.&lt;/p&gt;
&lt;p&gt;Mean age of their older cohort was 69.2 (SD 3.8). The oldest was 79.&lt;/p&gt;
&lt;p&gt;The researchers reported that 15.3% of the older patients were referred for optical colonoscopy on the basis of the CT results, compared with 7.9% of the overall screening group.&lt;/p&gt;
&lt;p&gt;Less than 4% of positive findings were determined to be false with the optical procedure (3.6% for polyps 6 to 10 mm in diameter, 2.1% for larger lesions).&lt;/p&gt;
&lt;p&gt;Of the 59 advanced neoplasias identified in the older patients, all but three were at least 10 mm in size.&lt;/p&gt;
&lt;p&gt;The scans also suggested abnormalities outside the colon in 89 (15.4%) patients. Of these, 45 received a full workup, which revealed substantial and previously unsuspected diagnoses in 21 cases  -- 18 were vascular aneurysms. The other three included one lung tumor, a femoral hernia, and a malrotation.&lt;/p&gt;
&lt;p&gt;Kim and colleagues reported that no &quot;substantial complications&quot; such as perforations or major hemorrhage occurred in the older patients, either with the CT scan or follow-up colonoscopy.&lt;/p&gt;
&lt;p&gt;They also indicated that the ratio of large to small neoplasias was similar in the older patients compared with their CT screening group as a whole. Histologic and morphologic findings were similar as well.&lt;/p&gt;
&lt;p&gt;The researchers cited the observational nature of the study, in which negative findings were not corroborated with optical colonoscopy, and its restriction to a single center as its main limitations.&lt;/p&gt;

      &lt;p&gt;Middle-aged patients with early knee osteoarthritis can benefit from either a self-managment program or strength training, but a combination of the two did not provide additional gains, a study found.&lt;/p&gt;
&lt;p&gt;During a two-year trial, roughly two-thirds of participants randomized to one of three groups achieved clinically meaningful improvements in functioning, defined as a 26% change from baseline, according to a new report in the Jan. 15 &lt;em&gt;Arthritis Care &amp;amp; Research&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;Patients also achieved clinically meaningful improvements in pain -- defined as a 40% change from baseline -- regardless of treatment group, wrote Patrick E. McKnight, PhD, of George Mason University in Fairfax, Va., and colleagues.&lt;/p&gt;
&lt;p&gt;The functional improvements were 70% for patients in the strength training group, 64% for those in the self-management group, and a 66% improvement in the combined treatment group. For pain, the breakdown was as follows: &lt;ul&gt; &lt;li&gt;Strength training, 65%&lt;/li&gt; &lt;li&gt;Self-management, 56%&lt;/li&gt; &lt;li&gt;Combined treatment, 65%&lt;/li&gt; &lt;/ul&gt;&lt;/p&gt;
&lt;p&gt;McKnight and colleagues wrote that studies in older patients have reported positive changes for both strength training and self-management.&lt;/p&gt;
&lt;p&gt;To see if these modalities also could benefit younger patients with milder disease, and whether combining the two would lead to additional benefits, the investigators recruited 273 subjects ages 35 to 64 years.&lt;/p&gt;
&lt;p&gt;Participants all had pain on most days in at least one knee, had symptoms for less than five years, had radiographic evidence of osteoarthritis, and had self-reported disability.&lt;/p&gt;
&lt;p&gt;The strength training program consisted of two phases, the first being nine months focused on stretching and balance, range of motion and flexibility, and isotonic muscle strengthening in three sessions each week.&lt;/p&gt;
&lt;p&gt;Phase two involved the development of self-directed long-term exercising habits, following the guidance and advice of trainers.&lt;/p&gt;
&lt;p&gt;The self-management program also included two phases. During the first nine-month phase, participants attended 12 weekly 90-minute classroom sessions addressing coping and self-efficacy skills, promoting active adaptive strategies and increasing perception of control for physical function and pain management.&lt;/p&gt;
&lt;p&gt;Phase two consisted of telephone calls from instructors and problem-solving discussions.&lt;/p&gt;
&lt;p&gt;The combined treatment group concurrently participated in both strength training and self-management programs, adjusted to maintain equivalent contact time with the other two groups.&lt;/p&gt;
&lt;p&gt;Overall compliance was modest, with 55.8% of those in the strength training group completing the study, along with 69.1% and 59.6% of the self-management and combined groups, respectively.&lt;/p&gt;
&lt;p&gt;Objective measures of physical functioning consisted of five physical performance tests measured at baseline and at months nine and 24. Pain and disability were self-reported.&lt;/p&gt;
&lt;p&gt;All of these outcomes showed significant changes over time in all three treatment groups, with effect sizes computed using the standard Cohen&apos;s d units: &lt;ul&gt; &lt;li&gt;Leg press, d=0.85&lt;/li&gt; &lt;li&gt;Range of motion, d=1.00&lt;/li&gt; &lt;li&gt;Work capacity, d=0.60&lt;/li&gt; &lt;li&gt;Balance, d=0.59&lt;/li&gt; &lt;li&gt;Stair climbing, d=0.59&lt;/li&gt; &lt;li&gt;Pain, d= &amp;#8722;0.51&lt;/li&gt; &lt;li&gt;Disability, d= &amp;#8722;0.55&lt;/li&gt; &lt;/ul&gt;&lt;/p&gt;
&lt;p&gt;Both men and women improved, although benefits were greater among men, who gained more large muscle mass strength. Study-related adverse effects included accident, injury, or increased pain with strength training.&lt;/p&gt;
&lt;p&gt;Within-group and between-group effect sizes were also computed. All within-group effect sizes differed significantly from zero, with the exception of the pain outcome in the strength training group, but none of the between-group effects were significant.&lt;/p&gt;
&lt;p&gt;&quot;The logic behind the combined treatment was that the different factors addressed in physical and psychological treatments might produce an additive effect if administered together. These results suggest otherwise,&quot; the investigators conceded.&lt;/p&gt;
&lt;p&gt;As to why there were no differences between the three treatment arms, the length of the study and the relative youth of the participants may have contributed.&lt;/p&gt;
&lt;p&gt;The sample was younger than are included in typical osteoarthritis studies and were higher functioning at baseline, which could mean that there was less opportunity to produce a significant effect, the investigators suggested.&lt;/p&gt;
&lt;p&gt;Also, the increased burden of the combined treatment may have diluted the effects of the two programs.&lt;/p&gt;
&lt;p&gt;Despite the fact that combined treatment in this study had negligible benefits beyond that seen with strength training and self-management, other long-term outcomes such as physical activity level might show a greater response. This remains speculative, but deserves further study, according to the investigators.&lt;/p&gt;
&lt;p&gt;Limitations of the study include the fact that the researchers did not assess effects of the treatment on articular cartilage or inflammation, and they did not include a no-treatment arm.&lt;/p&gt;
&lt;p&gt;Also, there may have been differences in self-medication practices between the groups.&lt;/p&gt;
&lt;p&gt;Nonetheless, the study findings suggest that the two nonpharmacologic approaches can produce gains in middle-age patients with osteoarthritis, and both can be recommended.&lt;/p&gt;
